Imagine a progressive community-minded play space where children and their parents alike can bond over music, theater and other lives performance, in between classes and gym time.

Dina Rosenbloom already has.

Rosenbloom is in the early stages of looking for space in the Fort Greene/Clinton Hill area to launch Rattle & Mum, a new kind of play space for children that she says doesn't exist elsewhere in Brooklyn.

“We want to be able to bring community together through music and performance,” said Rosenbloom, a Russian immigrant who spent several years in Minneapolis before moving to Brooklyn, where she lives with her family in Clinton Hill.

After having her first child in 2009, Rosenbloom said she quickly realized the neighborhood lacked resources for parents to entertain their children. “There's nothing in this area,” she said.

Instead of shlepping to childcare centers in Brooklyn Heights or Park Slope, Rosenbloom decided to start one of her own. Two years later, her business plan for the venture earned an honorable mention in Brooklyn Library's PowerUP! competition for aspiring entrepreneurs.

Rattle & Mum will feature an open space where children up to five-years-old can engage in a range of activities, and offer educational programs in a classroom setting as well.

Rosenbloom envisions hosting concerts, puppet shows and other live performances for audiences of up to 150 people. She hopes to open in 2012, and attract 250 members the first year. At $350 dollars for an annual membership, Rattle & Mum will be a bargain.

“When the weather is bad parents look for activities” for their children, she said, “especially in an urban environment.” Once her play space opens, Brooklynites will have another enticing option.
